The last great North American glacier began its retreat some 10,000 years ago, leaving behind the accumulation of boulders, sand, and clay that is now known as Martha's Vineyard. The ancestors of Wampanoag people have lived for at least 10,000 years at Aquinnah (Gay Head) and throughout the island of Noepe (Martha's Vineyard), pursuing a traditional economy based on fishing and agriculture. The Aquinnah Wampanoag share the belief that the giant Moshup created Noepe and the neighboring islands, taught our people how to fish and to catch whales, and still presides over our destinies. Our beliefs and a hundred million years of history are imprinted in the colorful clay cliffs of Aquinnah.

In 1972 the "Wampanoag Tribal Council of Gay Head, Inc." was formed to promote self-determination, to ensure preservation and continuation of Wampanoag history and culture, to achieve federal recognition for the tribe, and to seek the return of tribal lands to the Wampanoag people. The Wampanoag Tribe of Gay Head (Aquinnah) became a federally acknowledged tribe on February 10, 1987 through the Bureau of Indian Affairs (BIA). The Wampanoag trust lands are located in the southwest portion of Martha's Vineyard Island in the town of Gay Head. In accordance with 1987 Settlement Act with the federal government there are approximately 485 acres of Tribal Lands purchased (160 acres private and approximately 325 acres common lands). The common lands include the Gay Head Cliffs, Herring Creek, and Lobsterville, and the private lands include parcels I, IIA, IIB, and III (see map). Other land owned by the Tribe include parcels in Christiantown and Chappaquiddick. A master plan of Wampanoag Tribal Lands was developed in 1993 for approximately 160 acres of the Wampanoag Tribal Trust Land, comprising of parcels I, IIA, IIB, and III. The Master Plan followed several years of investigative efforts and illustrates the present vision of the future tribal community in Gay Head.
